Frequently Asked Questions
Will this let me plug a 3-prong appliance into a 2-prong outlet?
Yes. The TENINYU converter plugs into a two-slot wall outlet and gives you three AC outlets that accept three-prong plugs. Hair dryers, straighteners and lamps are among the listed compatible appliances.
How does the grounding work on this adapter?
Fasten the adapter with the faceplate screw of a grounded outlet box. Grounding protection depends on that screw connection, so if the box isn't grounded, the third prong won't be grounded either. If you aren't sure, check the box or ask an electrician.
How much power can it handle?
It is rated at 125V, 15 Amps and 1875 Watts maximum. That limit covers all three outlets together, so add up what's plugged in. Running two high-draw appliances like a hair dryer and a straightener at once can exceed it.
Does it block the other outlet on the wall plate?
No. The listing says the converter won't block the second outlet on a standard duplex receptacle, so the other outlet stays free.
Is this adapter safety certified?
Yes. It is UL Listed, and the housing is fire-resistant ABS. For current warranty terms, check the product listing or contact TENINYU.
